Instructions: You will see some situations and you need to write questions using PRESENT PERFECT SIMPLE or PRESENT PERFECT CONTINUOUS.
For example: A new student arrives in your class. You ask her, "how long/learn/English"?
So you need to write: How long have you been learning English?
IMPORTANT: Remember, it's a question, so use a question mark (?) at the end.
To acknowledge that you have understood the instructions, please type "YES" in answer to this question and move on to the next question
